In the example below, we are extracting first name from the full name. We are pulling first 4 characters from the variable name, substrn in sas. Incorrect Method: As shown in the image above, the first names of the last two individuals have a length greater than 4 characters.

Returns a substring, allowing a result with a length of zero. If string is numeric, it is converted to a character value that uses the BEST Leading and trailing blanks are removed, and no message is sent to the SAS log. If you do not specify length , the SUBSTRN function returns the substring that extends from the position that you specify to the end of the string. If you do not want the first argument to be evaluated as a macro expression, use one of the macro-quoting functions in the first argument. About This Book. CDF Bernoulli Distribution.

This tutorial explains how to extract last N characters or digits of a variable in SAS, along with examples. Suppose you have a product ID in which last 4 characters refers to a product category so you are asked to pull product category information. In this case, it is 10 characters long. See the image below. In order to make it run for numeric variables, we first need to convert numeric variables to character variables with PUT function. In this process, we first calculate the logarithm base 10 of the number , which gives us a result of 3. Then, by using the INT function, we extract the integer part of the logarithm, resulting in 3. Finally, by adding 1 to the integer part, we determine that the number has 4 digits. Deepanshu founded ListenData with a simple objective - Make analytics easy to understand and follow. He has over 10 years of experience in data science. In the first example, it returns 7 after subtracting 3 from productID. End result would return 7th, 8th, 9th and 10th character. In total it returns last 4 characters. If we want last 4 characters, then we would want the substr 's second argument be the fourth character's position from right to left, which is the length of the string - 3; If we want the last 5, then it should be the length - 4.

PMT Function. Date, Time, and Datetime Constants.

But apart from extracting parts of a string, it has another important use. The part begins with the character you specify in the start-position argument and the number of characters you specify in length. If the length of the returned variable is not defined, it is assigned with the length of the first argument. Note: The length of the resulting variable will be the length of the character value if the length is not previously assigned.

If you do not specify length , the SUBSTRN function returns the substring that extends from the position that you specify to the end of the string. COSH Function. If the length that you specify extends beyond the end of the string, the result is truncated at the end, so that the last character of the result is the last character of the string. In this case, it is 10 characters long. PEEK Function. Returns a substring, allowing a result with a length of zero. FINV Function. SDF Function. YYQ Function. STD Function. If the length that you specify extends beyond the end of the string, the result is truncated at the end, so that the last character of the result is the last character of the string. DS2 Function Examples. FACT Function. CDF Poisson Distribution.

Returns a substring, allowing a result with a length of zero. If string is numeric, it is converted to a character value that uses the BEST

INTZ Function. MAD Function. SDF Function. MORT Function. TRIM Function. See Also Functions:. MIN Function. Last updated: January 5, PCTL Function. The length of the result is reduced accordingly. Returns a substring, allowing a result with a length of zero. See Also. This has been demonstrated below; 1. BOR Function. For more information, see Internationalization Compatibility.
